Dreams about buildings often symbolize your sense of self, personal growth, or your current life situation. In your dream, the big house on the hills could represent a high point in your life or aspirations that you are reaching for. The great view suggests clarity and perspective, indicating that you may feel confident about where you are heading.

However, the crumbling building symbolizes a fear of loss or instability. Since you were trying to gather everyone, particularly your brother, it indicates a sense of responsibility or concern for your loved ones amidst a chaotic situation. The fact that some people did not make it could reflect feelings of anxiety about not being able to protect those you care about or fears of failure.

Moving to a new house after the chaos signifies a fresh start or a new phase in your life. However, discovering that the new house is haunted can represent unresolved issues or fears that you may be carrying from the previous experience. It suggests that even though you try to move on, some elements of your past still linger and affect your present.

Overall, this dream may be urging you to acknowledge any fears or anxieties you have about change and to confront unresolved issues to fully embrace new beginnings. It might be helpful to reflect on what aspects of your life feel unstable and consider ways to address them.
